The evolution of the NFL:
Take a look at how the NFL has evolved from its humble roots, and the efforts being made to ensure it continues to grow.

Ta'amu was chosen by the Steelers in the fourth round of the NFL draft but has yet to play in a game. He was suspended two weeks without pay last month following a run-in with police in the city's South Side neighborhood that resulted in more than a dozen charges, including multiple felonies.

Ta'amu was reinstated on Oct. 30 but remained on the inactive list. He pleaded not guilty to all charges during a court date last week and apologized for his actions while expressing hope he would remain with the team.

Gilreath spent the first nine weeks of the season on the practice squad.
